Hz Metavrx Layout SDK

What it does

When your agent uses it

• Apps that need multiple app-owned panels without an immersive scene
• Immersive Spatial SDK scenes

Example prompts

• “/hz-metavrx-layout-sdk”

What it can do on your machine

Read from SKILL.md and the folder at commit 3a8553d. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are kotlin and javascript).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Hz Metavrx Layout SDK loads about 855 tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 125 tokens; SKILL.md has 234 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~125

When it runs · the whole SKILL.md, loaded when a task matches

~855

With references · SKILL.md plus every file in references/, read only if the agent opens them

~12k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Build multi-window Meta Horizon OS experiences with the MetaVrx Layout SDK in Jetpack Compose or React Native. Covers framework selection, setup, anchoring, semantic offsets, window promotion, fallback, priority, lifecycle, and theming. Use for apps that need multiple app-owned panels without an immersive scene. Build path: Standard Android, including React Native; use hz-quest-verify-first if the path is unclear, and do not use this skill for immersive Spatial SDK scenes.
